Marianne Minnigerode Maigne (Polly) Hulfish, 75, a longtime resident of Alexandria, where she restored and renovated many houses in the city's Old Town district, died of cancer Saturday at Alexandria Hospital.

Mrs. Hulfish was born in Manila, the Philippines, and grew up in Alexandria. She attended the Felix Mahoney and the Corcoran art schools. For many years, she was a free-lance specialist in the restoration of early American furniture and ornaments.

In 1960, she founded Old Alexandria Restoration, Inc., a firm that bought, renovated and sold more than 45 houses in Alexandria. Mrs. Hulfish closed the business in the early 1970s. She later worked parttime at the Apothecary Shop, a pharmacy in Alexandria.

In July, the Alexandria City Council passed a resolution hailing Mrs. Hulfish for her work in restoration. In 1962 and 1968, she received awards of merit for her work from the Alexandria Association, of which she was a member.

Mrs. Hulfish also was a member of the Old Town Civic Association, the Alexandria Historical Association and the Penwomen's League.

Her husband, Thomas Andrew Hulfish Jr., died in 1976.

Survivors include a son, Thomas Andrew III of Alexandria, a daughter, Sherry Hulfish Browne of Washington; a sister, Frances Davidson Maigne of Alexandria, and three grandchildren.
